how do i correctly grip a circle change to maximize the deciption and movement of the pitch
Cut the ball in half with thumb and middle finger. Then tuck the index finger down the side of the ball as much as flexibility allows. If you can make a circle, great. If not, don’t - just make a “C”. Don’t cheat and let the thumb creep up the side of the ball towards the index finger. Finally, pronate to get the middle and ring fingers on top of the ball.
one more question, where do i put the pressure points?
it should be the thumb and your ring finger. But dont get mad if you cant throw it for a strike right away this pitch takes patience and a lot of it.
